The PM880 moisture analyzer is a complete, portable hygrometer for measuring the moisture/humidity content of industrial gases and liquids. With the combined experience and expertise of the former Panametrics and General Eastern businesses, the PM880 was designed to meet the most demanding process applications. Utilizing the proven aluminum oxide moisture sensor, the PM880 can express the absolute humidity of gases and liquids in dew point temperature, parts per million by volume (PPMv), parts per million by weight (PPMw), pounds per million standard cubic feet in natural gas, relative humidity, and other measurement units.
